Looks like you never took my advice and added that flex pipe to the midpipe to prevent this from happening.Also my 2j down pipe cracked again and the escaping hot gasses melted the o2 sensor wires and connector and shorted out my car causing it to completely shut off at 80mph ish 🤫 and the car wouldn't start so after talking to nissan egg he told me about the ipdm box under the intake and help me get my jukey working again! Now I bought a gtm downpipe and second cat delete from another member along with a new o2 sensor and some gaskets and studs so in short 2js not great design cost me $700 in replacement parts and misc. Gaskets and studs!
For the 1 billionth time, the 2J downpipe design is not flawed. I am NOT defending 2J (lord knows I'll do quite the opposite in private) but the problem is that once you go aftermarket exhaust, you lose all the spring bolts and YOU MUST INSTALL A FLEX PIPE or else you WILL crack your exhaust at its weakest point. That ribbed section in the 2J pipe is a vibration isolation section, NOT a flex pipe. To be clear: NO AFTERMARKET EXHAUST FOR OUR VEHICLE COMES WITH A FLEX PIPE. This is something you must do IN ADDITION to your purchases to guarantee longevity.
Like I told Mr. Noob forever ago... but he doesn't like to listen to me. He just likes to ask me questions and not follow my advice. :-|
